Background: Preoperative diagnosis of malignant collision tumors (MCT) is extremely difficult. The value of dermoscopy to improve the correct detection of these tumors has not been previously studied. This study aims to evaluate the diagnostic accuracy of MCT with and without dermoscopy and to describe the dermoscopic features of a large series of MCT. Methods: Dermoscopic images of 161 MCT were evaluated. Clinical and dermoscopic images of histopathologically proven MCT intermingled with other tumors were randomly presented to clinicians with different levels of experience, blinded to the diagnosis and objective of the study. The clinical and dermoscopic diagnostic accuracies were measured separately. Results: A total of 161 histopathologically proven cases of MCT were collected. The most frequent MCT was basal cell carcinoma-seborrheic keratosis collision tumor (CT; 37.9%), followed by basal cell carcinoma-melanocytic nevus CT (19.9%), and melanoma-seborrheic keratosis CT (6.8%). Diagnostic accuracy among experts on dermoscopy was 71.4%. The study included 119 participants. The percentage of correct diagnoses was 8% by naked eye examination and 36.4% by dermoscopy (p < 0.001). The presence of the malignant component in the cases of MCT was not recognizable in 19.1% of cases by naked eye examination and in 11.8% of cases by dermoscopy (p < 0.001). Conclusions: The diagnosis of MCT can be assisted and clarified by dermoscopy. However, many of these lesions manifest complex morphologies and continue to be challenging, even for experts on dermoscopy. Atypical, uncertain, or non-classifiable lesions still need a complete excision for the final diagnosis. [ABSTRACT FROM AUTHOR]

Erosive pustular dermatosis of the scalp (EPDS) is an uncommon disease and primarily affects older men who have photo-damaged bald scalp, as was confirmed by our case series. EPDS is probably an overlooked disease, whose diagnosis is often missed because of a higher incidence of other cutaneous diseases affecting the same area and usually secondary to chronic actinic damage, such as actinic keratosis, basal cell carcinoma, and squamous cell carcinoma. For the first time, we report a case series of misdiagnosed EPDS with the aim of understanding why a diagnosis of EPDS was initially missed and try to give some tips to avoid future diagnostic delay.

Background: Seborrheic keratoses (SKs) may sometimes mimic benign and malignant skin tumors, and a biopsy can be necessary in order to rule out malignancy.Methods: From the database of our pigmented lesion clinic, we evaluated the dermoscopic features of difficult-to-diagnose SKs that were biopsied between January 2010 and December 2014.Results: SKs represented 3.8% of all excised lesions (161/ 4,182). Specifically, 91 (56.5%) were excised to rule out melanoma, 63 (39.1%) to rule out squamous cell carcinoma and 7 (4.4%) to rule out basal cell carcinoma. The following 10 global dermoscopic patterns were identified: multicomponent (32; 19.9%); reticular (24; 14.9%), characterized by an irregular pigment network; bowenoid (21; 13.0%); hairpin (19; 11.8%); keratoacanthoma-like (16; 9.9%); blue-nevus-like (15; 9.3%); lichenoid (6; 3.7%); hyperkeratotic (6; 3.7%); clonal (5; 3.1%); spitzoid (5; 3.1%). Furthermore, 12 SKs (7.5%) were not included in any of such patterns (not classified).Conclusion: Our results are in line with previous studies highlighting the dermoscopic variability of SKs. Although excised SKs may be classified into 1 of 10 repetitive dermoscopic patterns, a biopsy remains mandatory for those that cannot be clearly differentiated from common skin malignancies.

- Abstract
Background: Radiotherapy is an established treatment for some types of patients with nonmelanoma skin cancer. A hypofractionated schedule has been proposed as a valuable option for elderly disabled patients to minimize the number of hospital visits.Objective: We sought to compare a weekly hypofractionated orthovoltage radiotherapy regimen with a standard daily one for the treatment of nonmelanoma skin cancer.Methods: A retrospective cohort study was performed on 436 tumors. Overall survival, disease-free survival, and cosmetic outcome were measured. Life-table analysis, Kaplan-Meier survival analysis, and multivariate Cox regression model were performed.Results: The hypofractionated regimen was not associated with increased recurrence rates and mortality, or with a poorer cosmetic outcome, when compared with the daily schedule.Limitations: Absence of complete information about acute treatment toxicity and a shorter follow-up time for patients receiving the weekly schedule are limitations of this study.Conclusions: A weekly hypofractionated regimen of orthovoltage radiotherapy seems to be the most appropriate approach in elderly disabled patients with nonmelanoma skin cancers.

- Abstract
Background: Biopsies and surgical excisions represent routine procedures in clinical settings dealing with skin cancer. Objective: To evaluate the impact of clinical examination, dermoscopy, reflectance confocal microscopy and digital monitoring on the decision to excise or biopsy a lesion in routine practice. Methods: Patients scheduled for biopsy or excision of a skin lesion were prospectively enrolled. The expert dermatologist was asked to select the main factor that prompted him/her to excise or biopsy the lesion. Results: The most common reason for melanoma excision was clinical and dermoscopic morphology (70.3%), followed by dermoscopy (11.4%), monitoring (8.9%) and clinical context (8.2%). Most basal and squamous cell carcinomas were recognized both clinically and dermoscopically, while 18.6 and 15.0%, respectively, could only be detected with dermoscopic examination. Conclusion: Each part of the clinical examination has a contributory role in the diagnosis of melanoma and other skin cancers. © 2015 S. Karger AG, Basel [ABSTRACT FROM AUTHOR]

- Abstract
Background: The term 'collision tumor' refers to the association of 2 or more different neoplasms within the same lesion. The association of a benign neoplasm with a malignant neoplasm is of particular significance and warrants diagnostic accuracy. Objective: The purpose of our study was to see if reflectance confocal microscopy (RCM) was a valuable tool when dealing with collision tumors. Methods: We retrospectively evaluated 24 histologically confirmed cases of collision tumors, which were initially assessed using dermoscopy and RCM. Results: The malignancy most commonly detected in association with collision tumors was basal cell carcinoma (BCC) (n = 13), followed by melanoma (n = 5, of which 2 collided with BCC) and squamous cell carcinoma in situ (n = 4). Seborrheic keratoses were the most common benign neoplasms found in association with collision tumors (n = 18), followed by nevi (n = 7). Dermoscopy revealed the malignant component in 14 out of 20 lesions compared to RCM, which revealed a malignant component in 19 out of 20 neoplasms. There was excellent concordance between RCM and histopathology with regard to the identification of a malignant component within a tumor (kappa value >0.9). Conclusion: The dermatoscope and the reflectance confocal microscope, when used in conjunction, are valuable tools aiding in the diagnosis of collision tumors. © 2013 S.

- Abstract
Nonmelanoma skin cancer refers to a broad class of tumors, including actinic keratosis, basal cell carcinoma, and squamous cell carcinoma, and as a group these are the most frequent cancers occurring in light skinned humans. In contrast to the rarity of amelanotic melanoma, nonmelanoma skin cancer commonly lacks pigmentation. Although these tumors rarely cause death related to metastases, they commonly destroy underlying tissues and should be removed at the earliest possible stage. Dermoscopy improves the clinical diagnosis of nonpigmented skin tumors by allowing the visualization of specific vascular structures that are usually not visible to the naked eye. Dermoscopic vascular patterns of several nonmelanocytic nonpigmented skin tumors, such as sebaceous hyperplasia, seborrheic keratosis, clear cell acanthoma, Bowen disease, or nodular cystic basal cell carcinoma are highly specific, allowing a ready diagnosis in most cases. Others, such as actinic keratosis, pyogenic granuloma, or uncommon adnexal tumors, may be difficult to differentiate even with the aid of dermoscopy. For this reason, general guidelines have been established to assist in making the most appropriate management decision. In the second part of this review of dermoscopic vascular structures of nonpigmented skin tumors, the dermoscopic patterns associated with benign and malignant nonmelanocytic skin tumors and recommendations for the management of these tumors will be discussed. Learning objectives: After completing this learning activity, participants should be able to recognize the vascular morphology, architectural arrangement of vessels, and additional dermoscopic clues of nonmelanocytic nonpigmented skin tumors, recognize the diagnostic significance of vessels associated with benign and malignant nonmelanocytic tumors, and apply rules for the management of these tumors.

Chondrodermatitis nodularis helicis (CNH) is a benign auricular disease whose differentiation with nonpigmented tumors is mandatory. Clinical characteristics of CNH are well known, but there is no information about the dermoscopic features that could help differentiate CNH from squamous cell carcinoma and other non-melanoma skin cancers. To describe the dermoscopic appearance of CNH and to formulate a differential diagnostic model, we conducted a retrospective, single center, observational dermoscopic study on a sample of 189 biopsy-proven lesions: 25 CNH; 26 squamous cell carcinomas; 62 basal cell carcinomas and 76 other benign and malignant tumors. Univariate and multivariate analyses were conducted by logistic regression. The most significant dermoscopic finding for CNH was a peculiar global configuration (daisy pattern), consisting of white thick lines, radially arranged, converging to a central rounded yellow/brown clod (an erosion covered by keratin or sero-crust). This pattern achieved 92 and 98% of specificity for discriminating CNH with squamous cell carcinoma and basal cell carcinoma, respectively. In conclusion, dermoscopy is valuable for the diagnosis of CNH as a first screening tool because of a consistent global dermoscopic configuration (daisy pattern), consisting of radially arranged white thick lines surrounding a central rounded yellow/brown clod.

Dermoscopy is a widely accessible, inexpensive, and reliable noninvasive diagnostic tool that improves the accuracy of the clinical diagnosis of skin tumors. Most dermoscopic patterns correlate with specific histopathologic substrates. Accordingly, dermoscopy allows a better differentiation between specific subtypes of skin tumors. The common benign epithelial skin tumors, such as solar lentigo and actinic keratosis, typically display specific dermoscopic criteria, which allow their clinical recognition. The dermoscopic hallmark of all vascular tumors is a mixture of red-purple-blue at times black colors, which however present with different patterns. Adnexal tumors are generally considered as dermoscopic mimickers of basal cell carcinoma, but specific clues exist, facilitating the differential diagnosis. The sensitivity and specificity rate of dermoscopy in the diagnosis of basal cell carcinoma is reported to be 9 and 93 %, respectively. Dermoscopy reaches 98 % sensitivity and 95 % specificity in the diagnosis of actinic keratosis. Dermoscopy reaches 79 % sensitivity and 87 % specificity in the diagnosis of squamous cell carcinoma.

Dermoscopy has become an integrative part of the clinical examination of skin tumors. This is because it significantly improves the early diagnosis of melanoma and non-melanoma skin cancer (NMSC) including basal cell carcinoma and keratinocyte skin cancer compared with the unaided eye. Besides its value in the noninvasive diagnosis of skin cancer, dermoscopy has also gained increased interest in the management of NMSC. Dermoscopy has been used in the preoperative evaluation of tumor margins, monitoring of the outcomes of topical treatments and post-treatment follow-up. This article provides an update on NMSC with special emphasis on dermoscopy in the diagnosis and management of basal cell carcinoma, actinic keratosis, Bowens' disease and squamous cell carcinoma.
